Adding a room to your Laveen home means tying a new foundation into an existing structure without cracking, settling, or mismatched grade. We've poured additions for homeowners across Laveen, from the Southern Avenue corridor to the 51st Avenue corridor.

We're a third-generation, family-owned concrete company built on the kind of work ethic you'd expect from a business run by a working firefighter — precise, dependable, and built to hold up under pressure.

Why Laveen Homeowners Trust Cortez Concrete for Room Addition Concrete Slabs & Foundations

Tying a new foundation into an existing home requires matching grade, managing differential settlement between old and new concrete, and keeping drainage working correctly around the addition. Laveen's rapidly suburbanizing former farmland sits near the Salt River floodplain, so drainage and grading get extra attention on every project.

Here's what our process accounts for:

Drainage planning so the addition doesn't redirect water toward your existing foundation
Isolation joints designed to manage differential settlement between old and new concrete
Precise grade matching so the new slab ties cleanly into your existing home's elevation
Engineered footings sized for your addition's structural load

Our Room Addition Concrete Slabs & Foundations Process

Site Assessment — We evaluate your existing foundation, grade, and structural tie-in points.
Excavation & Footings — Footings poured to the engineered specs for your addition's load requirements.
Slab Pour — The new slab is poured to match your existing floor elevation.
Grade & Drainage Tie-In — We regrade around the addition to keep water moving away from both structures.
Final Grade & Cleanup — Site restored and graded, ready for your framing crew.

Who We Build Room Addition Concrete Slabs & Foundations For in Laveen

Local Knowledge for Room Addition Concrete Slabs & Foundations in Laveen

Laveen is part of the City of Phoenix, so it permits through Phoenix, and its rapid shift from farmland to subdivisions brings a mix of new slabs and larger semi-rural lots.

Sitting near the Salt River floodplain, Laveen projects get extra attention to drainage and grading to keep water moving away from structures.

That local knowledge is the difference between room addition work that lasts and work that fails early — and it's why Laveen property owners keep calling Cortez Concrete.

A Family Name Arizona Has Trusted for Three Generations

We're not a franchise or a rotating crew of subcontractors. Cortez Concrete is a third-generation family business, run on the values our grandfather started with — show up, do it right, and stand behind it. With an active firefighter at the helm, that discipline and attention to safety shows up in every Laveen-area project we pour across the Valley.

Hire Cortez Concrete and you're working directly with the family whose name is on the truck — not a call center, and not a crew you'll never see again.
